PANEL FOR UPRIGHT P|AN os.

SPECIFICATION forming part of Letters Patent No. 315,447, dated April 7,18,85.

' Application filed March `26, 1884. (No model.) i

To all whom it may concern:

Be it known that I, C. F. THEoDoR STEIN- WAY, of the city, county, andState of New York, have invented certain new and useful Improvements inPanels for Upright Pianos, of which the following is a specification.

The panels used heretofore in upright pianos were either made entirelyclosed, which prevented the sounds from the strings to pass to theoutside, or they were made of ornamental fretwork, which was liable tocrack in course of time,- owing to the sh rinkage of the wood.

The object of my invention is to furnish panels for upright and otherpianos, organs, Src., which not alone permit lthe sound toescape freely,but which may be brought out in any desired design, plain and in relief,so as to extend thereby the scope of ornamentation applicable to thepanels of the different kinds of pianos.

In the accompanying drawings, Figure 1 represents a perspective view ofan upright piano-forte with my improved panels. Fig. 2is a detail frontview of my improved panel on a larger scale; and Fig. 3 is a horizontalsection of the same on line x x, Fig. 2.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the exterior frame of myimproved panel for npright and other piano-fortes, organs,l &c., whichis composed of two parts, a and b. This panel may be located at theupper or lower part of the case. The exterior part of the frame A ismade of suitable wood, in keeping with the wood from which the case ofthe piano has been made. A lining or backing, B, of wire-gauze, isclamped between the two parts of the frame A of the panel, the facesideof the lining B being covered with openwork filling C, of a suitableplastic materialsuch as hard rubber, imitation wood, &c.- which isapplied to the wire-gauze lining B by a suitable layer of cement, theconnection being re-enforced by a second layer of cement at the back ofthe lining, which acts in the nature of an anchoring on the wire-gauze,so as to retain the open-work filling securely in position.Thefwire-gauze lining B and the open-work lling C permit the free escapeof the sounds, and permit a more artistic treatnient of the panels, asthe designer is not confined to the heavy continuous lines of thefretwork, which latter has to be self-supporting and rigid, and-` doesnot permit the application of such delicate and iine-lined figures ascan be produced by :my improved construce' tion. by its entire baci;surface to the wire, gauze it is supported thereon in such a manner thatAsl the filling is cemented or anchored i 6o I no rattling noise` iscaused by the passage `of A i the sound-waves through the openings ofthe panel.

Upon the open-work filling O are cast the ornamental figures or designs,which may be differently colored or not, to suit the fancy.. The fillingforms a secure backing firmly re` enforced by the wire-gauze, and theornaments are cast upon the face thereof. The latter need notnecessarily be of a size sufficient] y large to artistically fill thepanel, fortheilling C pre- -sents a neat appearancepand relieves mo:

notony.

Having thus described my invention, I claim as new and desire to lsecureby Letters Patent- 1. As an article of manufacture, Ia panel for`musical instruments consisting of a' frameof two parts, a backing ofwire-gauze stretched I in said frame and clamped between said parts, andopen-work filling of plastic material cemented to said backing ofwire-gauze, sub1. V

stantially as described. A

2. A panel for the case of piano-fortes, organs, dtcwcomposed of anexterior frame, a

lining or backing of wire-gauze, an open-work filling of plasticmaterial cemented to said backing of wire-gauze, and ornamental figuresintegral with and cast in relief uponsaid openi work filling,substantially as described. 3. A panel for the case of piano-fortes, or-

gans, Stc., composed of an exterior frame, a

lining or backing of wire-gauze, an open-work` filling of plasticmaterial cemented to said f Vbacking of wire-gauze, a layer or coatingof cement applied to the back of said gauze for I anchoring said fillingin cemented position,

and ornamental figures integral with andcast in relief upon saidopen-work filling, snbstan-u tially as described.

In testimony that I claim the foregoing as my` invention I have signedmy name in the pres- Inu ence of two subscribing witnesses. i l i c. E.'rHEoDoR sTEINwAY.`
